EVAPORATOR.

Specication of Letters Patent.

Patented June 11, 1907.

Application filed February 27, 1906. Serial No. 303,296.

To r1.1/ whoml it may concern:

Be it known that I, FRANK KLEIN- sCnMIDT, a citizen of the United States, residing at Doyle, in the county of Erie and State of New York, have invented certain new and useful Improvements in Evaporators, of which the following is a specification.

My invention relates to improvements in evaporators, for evaporating glue, and other substances.

The objects of my invention are, the production of an evaporator of simple construction in which a revolvin agitator is provided with heads connected y steam-conductin or heating pipes and to provide the inlet hea with a steam distributer `so that the steam is distributed tothe various heati -pipes in approximately equal quantities, t ereby avoiding the uneven heating of said pipes which would cause them to warp and break at the joints; and to otherwise improve on cvaporators now in use.

With these objects in view the invention consists in the combination, construction, and arrangement of parts tobe hereinafter described and more particularly pointed out' in the appended claims.

In the drawings,-Figure lis a central longitudinal section through an evaporatingapparatus embodying my invention. Fig. 2 is a vertical transverse section taken on line 2 2, Fig. 1.

Referring to the drawings in detail, corresponding numerals of reference refer to corresponding parts in both figures.

The reference numeral 1 designates the chamber which is closed and provided at its lower end with hopper extensions 2, having secured thereto outlet-pipes 3 for the re- Y moval of the evaporated substance from lthe chamber. Said pipes may be provided with suitable valves to confine the substance Wi th- Y The pass. As shown in preferred form in the drawings, each section of the chamber is provided with an escape outlet, and all pipes' connected to said outlets merge. into as i le vapor escape pipe 7a through which n51e vapors' escape into a va'cuum chamber, as is common.

Arranged lengthwise -in the lower end of the chamber is a combined heating and agitating-apparatus 8 comprising an inlet-head 9, an outlet head 10, and steam-pipes 11 connecting said heads. The inlet-head is provided With a center inlet tube l12, which passes through a stuffing-box 13 in the adj acent end wa of the chamber, and the outlet-head is provided With a center 'outlet-- tube 14 passing through a stuiiing-box 15 in the other end wall ofv the chamber. Said tubes serve as a shaft for the heating and agitating-apparatus, to which power may be transmitted in any practicable manner to revolve the same. 'The relative arrangement of the heating-pipes which connect the heads is such, that on revolving the heating-apparatus, the substance is thoroughly agitated to aid in the elimination of the Water-element.

As the heating-pipes are connected to the 4heads at different points, I make provision for distributing the steam entering the inlethead through tube 12, to prevent the passin of more steam through the pipes nearersai tube 'than through the pipes more remote therefrom. For this purpose I provide 'a distributer 16 within the head in the form of achamber having its peripheral wall provided with perforations 17 through which the steam issues; the steam being thereby distributed and expands within the head so as to 'pass in a proximately equal proportions through the eating-pipes. In this manner the various pipes are subjected to like temperature and necessarily compelled to expand equally; thereby preventing warping of any of the pipes, which would cause the heads to be subjected to uneven and twisting IIO strain, causing the pipe 6 to become loosened from the heads and consequently permitting the escape of steam into the chamber, in consequence of which water-elements would be added to the substance in greater quantities than could be eliminated.

The outlet-tube 14 is journaled to revolve in a iixed support 18, and secured to said tube and bearmg against opposite sides of said support, are collars 19, which revent lengthwise movement of the outlet-tu e. In consequence of this arrangement, the heating-apparatus must expand in the opposite direction.

Entering the outlet-tube through a stutlingbox 2O therein is a steam outlet-pipe 21 which is rovided at its inner end with a depending eg 22 extending into the outlet ead vto within a short distance of the bottomA of the latter, said leg terminating by preference in a flaring mouth. The steam entering the outlet-head through the heating-pipes secur/ed thereto passes out throu h pipe 21, and by`reason of said pi e exten ing closely to the. eripheral wall o the head, the water of con ensation remaining in said head can readily escape. By reason of the pipe 21 passing through a stuling-box on the outlet centertube,` the latter may turn with the heatingapparatus while said ipe remains stationary. The substance wit 'n the chamber has its level a distance from the top of the agitator, andwhen subjected to heat and agitated, it has a tendency to boil and enter the esca e pipes 7. To prevent this, I suspend a ba eplate 23 centrally from the top wall by means of bolts 23a, so as to hang in a direct line with the esca e-pipes. On either side of said plate an sllghtly beneath, side ballelates 24 are 'arranged and riveted to the si es of the chamber. Said side plates are inclined toward the longitudinal center of the chamber and overlap the center baffle-plate; the overlapping portions being separated from the center-plate by intervening spaces 25. In this manner a circuitous passage is provided for the vapors and the substance Within the chamber, when boiling strikes against the baffle-plates and is'checked in its upward course. The substance, when striking the center baflle-plate, drips onto the inclined side plates and is directed back into the chamber. Y

By the employment of aclosed chamber having the vapor-escape pipes and the charging pipe, the apparatus may be run continuously, the chamber being charged as the substance is drawn otl through the outlet-pipes 3.

Having thus described my invention, what Iclaim is,-

1. In an evapor'ator, the combination of a chamber, and a heating-ap aratus within the chamber comprising a hollow inlet-head, ahollow outlet-head, and a series of heatingpipes connecting said heads, said inlet-head having a steam-inlet and a steam-distributer into Which said inlet opens and which serves to distribute the steam to said heating-pipes, and said outlet head having a steam-,outlet 2. In an evaporator, the combination of a chamber, and a heating-ap aratus within the chamber com rising a ho low inlet-head, a hollow outletlead, and a series of heatingpipesconnecting said heads, said inlet-head having a steam-inlet and a perforated chamber into which said inlet opens 'and which serves to distribute the steam to said heating-pipes, and said outlet head having as teamoutlet.

3. In an evaporator, the combination of a chamber, and a heating ap aratus within the chamber com rising a ho low inlet-head, a hollow outletead, and a series of heatingipes connecting said heads, said inlet-head aving a steam -inlet and also a chamber therein into which said inlet opens and which has peripheral apertures for the escape of steam into said head, and said outlet head havin a steam-outlet.

4. Fn an evaporator, the'combination'of a chamber, and a heating apparatus within said chamber comprisin hollow cylindrical heads connected by para] el pi es, one of said heads having an inlet-tube an a steam-distributer in the form of a chamber extending into said hollow head from one Wall of the latter, said chamber having its peripheral wall rovided with perforations and the said in et-tube opening thereinto, and the other head having a steam-outlet. 4

In testimony whereof, I have affixed my signature in the presence of two subscribing wltnesses.
